369 +##ChartMuseum is being deprecated. After the migration is complete, **all harbor charts will be removed from ChartMuseum**, and **old HTTP(S)-based chart repositories will no longer work in Rancher (for internal harbor charts)**.##
370 +
371 +To ensure a smooth transition, we recomment should **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase.
372 +
373 +We will make your charts available in the corresponding new `<pkey>-helm` OCI projects.

377 +## Terminology##
378 +
379 +| Term | Meaning |
380 +| |-|
381 +| **Old Repository** | The existing HTTP/HTTPS ChartMuseum repository. |
382 +| **New Repository** | The new OCI-based Helm chart repository created for your project (e.g. `<chart-repo-name>` in `<pkey>-helm`). |
383 +
384 +-----
385 +
386 +## Why This Migration Is Required
387 +- ChartMuseum is deprecated and will be removed.
388 +- Applications deployed from old repos keep a reference to that repo inside their labels.
389 +- Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions**.##
390 +
391 +-----
392 +
393 +## Migration Steps##
394 +
395 +### 1. Create the New OCI Repository in Rancher##
396 +
397 +1. Go to **Apps → Repositories**.
398 +2. Add a new repository of type **OCI**.
399 +3. Name it exactly like your old repo name (e.g. `<chart-repo-name>`).
400 +4. Point it to the new OCI endpoint.
401 +
402 +-----
403 +
404 +### 2. Disable the Old ChartMuseum Repository Temporarily
405 +This step ensures that Rancher resolves charts from the new OCI repo.##
406 +
407 +1. Go to **Apps → Repositories**.
408 +2. Disable the old HTTP(S)-based repository.
409 +3. Keep it disabled until the migration is done.
410 +
411 +-----
412 +
413 +### 3. Update Existing Applications to Use the New OCI Repo
414 +Applications deployed with the old repository still contain the old repo name in their metadata.
415 +You must upgrade them once to transition.##
416 +
417 +1. Go to **Apps → Installed Apps**.
418 +2. Open the application that was deployed using the old repo.
419 +3. Click **Upgrade**.
420 +4. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
421 +5. Choose the chart version you want to deploy (same or newer).
422 +6. Click **Upgrade**.
423 +
424 +After this upgrade:
425 +- Your application is now linked to the **new OCI repository**.
426 +- Rancher will show upgrade notifications only for versions available in the new repo.
427 +
428 +-----
429 +
430 +### 4. Re-enable the Old Repository (Optional)
431 +If you still need the old repo for other apps, re-enable it after the migration steps above.##
432 +
433 +> Note: Even if a newer chart version exists in the old repository, your migrated app **will not see it**, because it is no longer connected to that repo.
434 +
435 +-----
436 +
437 +## Reverting the Migration (If Needed)
438 +If you want to move an app back to the old repository:##
439 +
440 +1. Temporarily disable the new OCI repo.
441 +2. Enable the old ChartMuseum repo.
442 +3. Open the application → **Upgrade**.
443 +4. Select the chart from the old repo.
444 +5. Save.
445 +
446 +This will reconnect the app to the old repository.
447 +
448 +-----
449 +
450 +## Summary
451 +- Add new OCI repo → disable old repo → upgrade apps → reconnect to OCI repo.
452 +- After upgrade, apps no longer track versions from the old repository.
453 +- Old repository will stop functioning after ChartMuseum shutdown, so migration is required.##
454 +
455 +-----
456 +
457 +If you want, I can also generate:
458 +- a shorter version (1-pager),
459 +- a diagram,
460 +- a Rancher UI screenshot guide,
461 +- or a version tailored for your team’s internal wiki.
